IF your cam bearings were original, i have been told that PMD use to finish hone some/all cam bearings to correct for machining tolerances/dimensional shift, that would not allow the cams to be installed wo this cam journal line hone.
I have had a couple builds that i could not put a cam in upon taking it out of the machine shop. One 455, One IA2 rebuild w teflon coated cam bearings, Each time Block went back, cam journals were line honed and NEW bearings installed, no further issues. Needs to be done perfectly so crush is maintained.
Since then i always bring the cam when i drop off the so they can prefit cam, to insure issue free build once i get it home. Time is money both ways.
